Introduction to Vue.js authentication
Vue.js authentication is defined as the process of checking or identifying the user’s identity on the vue.js app and the authentication is a crucial part of every app or website where the authentication is a feature of all these apps and websites to maintain the proper security of the user’s credentials which are handled by using username and passwords which are only known to the users itself and the system (if he/she saves). As Vue.js alone cannot handle the entire authentication so to create a vue.js authentication in the app using JWT( JSON web tokens).
Working of Vue.js authentication
In this article, we will discuss how authentication is provided in vue.js apps to the users. In vue.js apps to create proper authentication or verification of user’s credentials such as username or passwords the vuw.js apps use JWT tokens to maintain the proper privacy of the user’s credentials and there are many different ways also for authenticating users in vue.js apps such as Auth0 management dashboard to create a login and logout pages for user’s authentication.
In the below section, we will see about JWT (JSON Web Tokens) which are used in the creation of the authentication page of users in vue.js apps. Now let us see how it works when we use JWT tokens which are only used to handle the authentication at the front-end authentication. In this article we first we will see the JWT authentication option in vue.js apps as it provides straightforward solutions without depending on any 3rd party services to implement authentication on your vue.js apps.
The JWT authentication method working is very simple to understand. Firstly, when we want to create an authentication process in our vue.js apps we need to have a login and logout page for the users to log into the apps only who are already registered or have their proper login credentials such as username or emails and passwords only then those users can log into our vue.js apps else no one can log in. Then when the user enters the credentials these details are sent to the server where it will cross-check in the server and if the details match then the user can easily log in and this is when the server will send a token which is usually stored in the local memory of user’s browser and these tokens are used whenever the user calls an API of the app for any private information some other time where there is a copy of this token maintained which is sent to the user along with the request made through API request call. Then the server will collect this request of the user and it will decrypt the token provided if the users holding permission to access to private data which was requested by the users and if the server approves the permission then the details are verified and send the authentication details to the users or clients. After fetching these details and then the user logouts from the vue.js apps then the tokens which were stored in the local memory of the user’s browser is cleared so that there is no token copied for any hacking and hence the authentication process is a very crucial process in apps to maintain privacy details of users or clients.
Now let us see another way of authentication in vue.js apps and it is known as Auth0’s authentication service. So before using this we have to get a domain and client ID to get the application keys which are used for configuring the Auth0 which will callback the URL in your application to check and this Auth0 redirects the user after the user is authenticated and this must be notified or entered in Allowed Callback URL option in the application settings tab if it fails to then the user cannot log into the app where there is a possibility of a user getting a login error page. Similarly, we need to do this for logout also with the Allowed Logout URLs field to be entered in the application settings. Similarly, we must also whitelist the Allowed Web Origins field in the application settings so that the tokens automatically refresh with new tokens so that the user can be properly logged out after refreshing the page or using it for the next time. So after creating these callback routes the Auth0 contains idTokenPayLoad which holds the user details so that it can cross-check and verify the user details.
Vue.js applications can also use Vue-router which is a very efficient tool for handling the authentication in vue.js apps which will help users to check out their routes and can prevent accessing other routes that are not authorized.
So now let us see how the authentication page can look like in the below screenshot which will have fields like username and password which are entered by the users or clients to login to the vue.js apps.
So when the user enters the username and password which have a username as “test” and the password is hidden to again maintain privacy and this would look like
Now if the user has entered the details and the credentials are verified from the server then the client or user gets logged in easily and it can see it as below.
Now suppose I had given username and password both as “test” and if we enter the wrong password then it will give an error page saying either of your username or password is incorrect and this can be seen in the below screenshot.
So these above screenshots are the authentication page samples that look like in any vue.js apps or websites with different color or background features and some apps may even use email ids instead of a username for authentication which you can directly do if you are already logged in using email ids.
In this article, we conclude that the vue.js app’s authentication which is the process of authorization of users or clients for the vue.js app login process. In this article, we saw how the vue.js authentication uses JWT tokens, and it’s working we also another way of authentication in the vue.js app using Auth0 CLI. In this article, we can say that the authentication process is a crucial part of any apps or websites so that the user’s credentials are maintained with privacy using the above-discussed ways.
